CANOPY ROCKING FAN.

To all whom it may concern: V

, Be it known that I, EM L F. H RRMANN, a citizen of the United States,residing at can Baxter avenue, Louisville, in the county of Je-ffersonand State of Kentucky, have invented anew and useful Canopy Rocking Fan,of which the following is a specificati-on.

This invention relates to fan attachments for chairs or the like and hasfor its principal object to provide a fan which is actuated by therocking movement of the chair.

Another important characteristic of this invention resides in theprovision of a fan, an oscillating blade and a set of rotary blades, theoscillating blade imparting mo tion to the rotary blades.

Another object of this invention is to provide a device of thischaracter which is simple, durable and efficient in its construction andwhich may be manufactured at a nominal cost.

With these objects in View, others will appear as the followingdescription is taken in connection with the accompanying drawings; inwhich Figure 1 is a front elevation of my device showing the sameattached to the-back of a chair. Fig. 2 is a side elevation showing thechair in section. Fig. 3 is a modified form of my invention showing aweight in the place of the oscillating fan blade.

Referring to the drawings in detail 1 designates a top rail of the backof a rocking chair of any common construction on which is secured abracket 2. This bracket 2 is preferably formed of wood and issubstantially L-shaped as shown in Fig. 2. One extremity of the bracketis bifurcated to provide the divergent legs 3, the lower eX- tremitiesof the legs being formed with substantially U-shaped feet as at 4, thefeet engaging the rail 1 and held in rigid position thereupon by meansof the set screws 5. Owing to the peculiar shape of the bracket it willbeseen that when the same is in applied position upon the chair the freeextremity thereof will be disposed directly above the seat of the chair.

Vertically arranged upon the free extremity of the bracket andintersecting the same at right anglesis a U-shaped yoke 6. One of thearms of the yoke 6 is extended through the bracket at a point remotefrom the free end thereof as at 7, while the re- Application filed June1, 1914. Seria11\To. 842,333.

maining arm is secured to the free end of the bracket as at 8; Thus itwill be seen that the semicircular portion of the yoke is disposed uponthe upper side of the bracket while the extremities of the arms varedisposed upon the under side. To form a rigid support for the yoke andto keep the same in proper position upon'the bracket, Ihave provided thelatter with a bearing plate 9,:

the same being of U-shaped formation. and having'the free ends thereofsecured to the upper sides of the bracket, while the upper end thereofengages the medial portion of the yoke 6. The opposite sides of thebearing plate 9 are provided with alined bearings in which is journaleda shaft 10, the shaft being arranged at right angles to the bracket andhaving its opposite extremities provided with fan blades 7 11 which areof any suitable construction. Pivotally mounted upon the bracket andbetween the parallel arms of the yoke 6 is the upper extremity of a fanblade 12, the same depending from the bracket and adapted to oscillatewhen rocking movement is imparted to the chair. Wound about the shaft 10is a cord 13 the extremities of which are trained around pulleys l4journaled in the ends of the yoke 6, and have their extremities securedto the opposite sides of the fan blade 12.

It will be seen from this construction that when oscillatory motion isimparted to the blade 12 the cord 13 will be moved over the pulleys 14whereby rotary motion will be imparted to the shaft 10 to cause the fanblades 11 to rotate first in one direction and then the other, thedirection of rotation depending upon which way the blade 12 is moved.

In practice the bracket is secured to the back of the chair as shown inFigs. 1 and 2 so as to cause the free end of the bracket to be disposeddirectly above the seat of the chair; WVhen the occupant imparts rockingmotion to the chaiiythe blade 12 being free to swing, the inertia of theblade will cause the same to oscillate or swing upon its pivot, therebycausing a fanning of the air in close proximity to the occupant. Uponmovement of the blade 12 rotary motion is imparted to the blades 11,first in one direction and then in the other, through the medium of thecord 13 as has been described. Thus it will be seen that further fanningof the air is accomplished in addition to the moving of the blade 12. Ithas been found in practice that the rotary blades serve to keep fliesand other troublesome insects out of the zone of the occupant, while theoscillating blade 12 agitates the air sufiiciently to keep the operatorcool.

In Fig. 3 I have shown a modified form of my invention, in which I havesubstituted a weight 15 of any suitable construction, in place of theblade -12. Owing to the fact that the weight 15 has less air resistancethan the blade 12, a greater speed is imparted to the rotary blades, aswill be under stood. The Weight 15 is substituted for the blade 12 whenit is desired to use only the rotary blades for agitating the air.

Although I have shown and described a specific form of fan, I wish it tobe understood that various changes in the size, shape, proportion andminor details of construction maybe made without departing from Copiesof this patent may be obtained for five cents each, by addressing theCommissioner of Patents.

the spirit and scope of the appended claim.

What I claim is A fan attachment for chairs comprising a bracket aU-shaped yoke secured to one yoke, a member pivotally mounted upon 1said bracket between said pulleys and depending from said bracket, ashaft journaled in said bearing plate and having the oppositeextremities thereof provided with blades, and a cord Wound about saidshaft and passing over said pulleys and having the opposite extremitiessecured to the opposite sides of said member.
